You were helping me with my computer not powering up, except when I removed the network card. You suggested the pci controller was bad, and I should change the motherboard. I finally obtained a new motherboard and it seems to have corrected the problem. The only curious thing is that when I first plugged in the computer, it did the same thing...it wouldn't power up until I pushed the power button a bunch of times....but once it started and I shut it down, it starts on the first push of the power button every time. Any thoughts on why it wouldn't work the first time?

Re: Motherboard worked, but not on first try.
Its proberally because your card got a static charge,, This needed to be discharged , it happend when you pushed the button several times therefore dumping the eletricity.. Since it was dumped it started to work as normal without fault :) cheers..

First remove any power cables and batteries(if laptop) from your system and hold down the power button for 15 seconds.
Plug the power cable back in & attempt to boot. If this does not solve your problem then you will need to remove all non-essentials from your system.
If laptop, this simply consist of battery, ram, optical drive & any other removable bays or devices. Unplug all cables except the power cable & attempt to boot.
If desktop, you will need to remove any cables plugged into your computer except keyboard, mouse, power, video, sound, & network cable. Open the case & remove any PCI cards, except video cards, unless you have on-board video, unplug the data & power cables going to the optical & hard drives. Now attempt to boot. If you have no luck you can remove your RAM sticks & try again. If you get an error beep warning you about no ram then you might have a bad ram stick. If none of the above works then you may have a bad power supply or motherboard. Power supplies are pretty easy to test with tester or use a spare.
I need more info before I can help much. Try this if possible.
is the network adapter park of the motherboard or is a separate PCI card?
If you can remove the card, I would remove it and restart the pc. Then
turn off the computer and reinsert the card. Power the PC back up and
see if windows even detects a device added. If it does not, then the
card may be toast.
Some history would be appreciated. Has this computer ever worked? Have you recently added new hardware or software? Has anything happened recently that may have caused this (lightning storm, etc.)?
If the computer was working fine and for no apparent reason now won't POST, first remove everything from the outside (keyboard, mouse, etc.) except monitor. If that works, one of the items you removed is causing a problem.
If not, unplug power, open case, remove all expansion cards except for video, then try again. If you have never worked inside a computer, some help from a knowledgeable friend would be advised. Be sure to touch the metal case before touching any circuit board inside the computer. Also disconnect the cabling from all of the drives and then retry boot.
Let me know if this helps. If not, we can do more providing you are comfortable working inside the computer at my direction.
Based on what you said, network card is not the main problem it is on the expansion slot where you had put the network card. My advice is that you should try putting your network card on other expansion slot or try another card (which is working) and put in on the slot to where you previously put your network card and if it doesn't work, that slot may have been damaged or it may have dirt inside.
